IPC: G06F3/0346
Filed: 1992-10-16
Abstract: Several different embodiments are disclosed of a simple, compact or miniature bar code scanner which is capable of scanning in any one of several modes. In a preferred embodiment, the compact bar code scanner is used in a small housing mounted on an index finger of an operator such that the natural pointing direction of the index finger aims the scanner. In one embodiment, a high frequency flexural member, with a scanning mirror and permanent magnet mounted thereon, is supported by a low frequency flexural member. An x drive coil is positioned by the permanent magnet, and with an applied high frequency x drive signal, causes the high frequency flexural member, with the permanent magnet means and scanning mirror mounted thereon, to torsionally oscillate at the frequency of the x drive signal. A y drive coil is also positioned by the permanent magnet, and with an applied low freduency y drive signal, causes the low frequency flexural member to oscillate to cause low frequency y scanning of the scanning mirror, thereby resulting in a raster scan pattern. With an applied high frequency y drive signal, the y coil causes the high frequency flexural member to oscillate at a high frequency to cause high frequency y scanning of the mirror, thereby resulting in an omnidirectional scan pattern. In several disclosed embodiments, the present invention provides a mirrorless beam scanning unit mounted in a finger size ring wherein a light emitter such as a visible light diode is moved back and forth.

Title: Systeme informatique insensible aux defaillances
Inventor: MAJOR DREW
IPC: G06F15/16
Filed: 1991-08-09
Abstract: L'invention est constituée par une méthode et un appareil permettant d'obtenir un système de sauvegarde insensible aux défaillances tel que, en cas de défaillance du système de traitement primaire, un système jumeau puisse prendre la relève sans interruption. L'invention permet d'obtenir un logiciel de sauvegarde. Deux serveurs sont utilisés, un serveur primaire et un serveur secondaire. Ces deux serveurs sont connectés par l'intermédiaire d'un canal de communication. Un système d'exploitation est associé à ces serveurs. La présente invention divise ce système d'exploitation en deux «moteurs». Un moteur d'entrée-sortie est responsable de la prise en charge et de la réception de toutes les données et de tous les événements asynchrones dans le système. Ce moteur commande les dispositifs physiques et leurs pilotes et est interfacé avec eux. Le moteur du système d'exploitation est utilisé pour opérer sur les données reçues du moteur d'entrée-sortie. Tous les événements ou toutes les données qui peuvent provoquer un changement d'état du système d'exploitation sont canalisés par l'intermédiaire du moteur d'entrée-sortie et sont convertis en un format de message. Les moteurs d'entrée-sortie des deux serveurs sont coordonnés l'un avec l'autre et fournissent les mêmes suites de messages aux moteurs du système d'exploitation. Ces messages sont mis dans une file d'attente accessible aux moteurs du système d'exploitation. Par conséquent, quel que soit la chronologie des événements (c.-à-d. des événements asynchrones), chaque moteur du système d'exploitation reçoit tous les événements séquentiellement sous la forme d'une chaîne séquentielle continue de données. Comme résultat, ce moteur est un automate à états finis comportant une «vue» d'entrée unidimensionnelle du reste du système et les états des moteurs du système d'exploitation des serveurs primaire et secondaire convergent.

Title: Intensity dividing device
Inventor: JENKINS RICHARD M
IPC: G02F2/00
Filed: 1991-12-02
Abstract: An intensity dividing device (10) incorporates a rectangular multimode waveguide (20) connected to an input waveguide (18) and a set of four output waveguides (22). The input waveguide (18) provides a fundamental mode input excitation of CO2 laser radiation to the multimode waveguide (20). The input waveguide (18) is offset from the multimode waveguide longit-udinal axis (24). Consequently, both symmetric and antisymmetric modes of the multimode waveguide (20) are excited. Mo-dal dispersion along the multimode waveguide produces electric field intensity maxima of differing magnitude centred on respective output waveguides (22). This provides division of the input radiation into a range of differing intensity outputs.
